A first proximity sensor 116 may be near the appliances and/or a second proximity sensor 118 may be positioned in an entryway of the building in various embodiments. In some embodiments, the building may be a home and the appliances may be home appliances.

In various embodiments, the apparatus 102 may include a sensor data module 120, an appliance state recognition module 122, a response module 124, and a transmission module 126. In some embodiments, the sensor data module 120 may be to identify sensor data in one or more signals relating to data from one or more sensors associated with an appliance (e.g., temperature, accelerometer, and/or contact sensors of sensor devices 110, 112, 114). In various embodiments, the sensor data module 120 may log and/or aggregate data from one or more sensors for later use by the sensor data module 120 and/or other modules.

In various embodiments, the appliance state recognition module 122 may be to determine an appliance state (e.g., not full, fill, running, and/or done dishwasher appliance states) of the appliance based at least in part on the sensor data. In some embodiments, determining the appliance state may include detecting an appliance state. In some embodiments, the appliance state recognition module 122 may be to determine the appliance state based at least in part on one or more of accelerometer or temperature data. In various embodiments, the appliance state recognition module 122 may be to determine the appliance state based at least in part on first temperature data from a first temperature sensor (e.g., temperature sensor of sensor device 110) and second temperature data from a second temperature sensor (e.g., temperature sensor of sensor device 112 or 114). In some embodiments, the appliance state recognition module 122 may be to determine the appliance state based at least in part on a probabilistic model. In various embodiments, the appliance state recognition module 122 may be to detect a door opening motion and/or determine an open door time duration based at least in part on the sensor data. In some embodiments, the appliance state recognition module 122 may be to determine the appliance state based at least in part on the open door time duration.

In some embodiments, the response module 124 may be to determine a response based at least in part on the appliance state. In some embodiments, determining a response may include developing and/or assembling a response. In various embodiments, the response module 124 may be to determine the response based at least in part on proximity data from one or more of the first proximity sensor 116 and/or the second proximity sensor 118 and based at least in part on the appliance state. In some embodiments, the presence of a user in a home may be detected by the second proximity sensor 118 and/or the presence of a user near an appliance may be detected by the first proximity sensor 116, and the response module 124 may generate a response based at least in part on the detected presence of a user. In some embodiments, the response may be a recommendation for a user action (e.g., unload dishwasher, move clothes to dryer).

In various embodiments, the transmission module 126 may be to send the response to at least one of an appliance controller for the appliance, such as appliance controller 128 associated with the dishwasher 104, or a presentation device such as a mobile device 130 (e.g., a smartphone) or other presentation device 132 (e.g., a display on a refrigerator, visual output on a counter, or an audio device such as a speaker). In some embodiments, one or more appliance controllers, not shown for clarity, may be associated with the clothes washer 106 and/or the clothes dryer 108. In some embodiments, the response may be a notification that may be sent to a user (e.g., a message to mobile device 130).

In some embodiments, the apparatus 102 may also include a behavior modeling module 134. In various embodiments, the behavior modeling module 134 may be to determine a user behavior profile based at least in part on usage of the appliance (e.g., time of day a user typically runs or never runs the appliance). In some embodiments, the response module 124 may be to determine the response also based at least in part on the user behavior profile.

In some embodiments, the apparatus 102 may include a processor 136. In various embodiments, one or more of the sensor data module 120, the appliance state recognition module 122, the response module 124, the transmission module 126, and/or the behavior modeling module 134 may be operated on the processor 136. In various embodiments, one or more of the sensor data module 120, the appliance state recognition module 122, the response module 124, the transmission module 126, and/or the behavior modeling module 134 may be implemented in hardware, firmware, a field programmable gate array (FPGA), an ASIC, or some combination thereof. In some embodiments, one or more of the sensor data module 120, the appliance state recognition module 122, the response module 124, the transmission module 126, and/or the behavior modeling module 134 may be operated on one or more processors in a platform arrangement. In various embodiments, the sensor data module 120 may be a sensor data identifier, the appliance state recognition module 122 may be an appliance state detector, the response module 124 may be a responder, the transmission module 126 may be a transmitter, and/or the behavior modeling module 134 may be a behavior modeler. In some embodiments, the processor 136 and/or one or more of the sensor data module 120, the appliance state recognition module 122, the response module 124, the transmission module 126, or the behavior modeling module 134 may be located in the same setting or building as the appliances. In other embodiments, one or more of the processor 136 and/or the modules may be located in a different setting or building as the appliances. In some embodiments, sensor data from one or more of the sensors may be routed through a gateway (not shown for clarity) to one or more processors and/or modules located in a remote setting such as a cloud computing system. In various embodiments, the apparatus 102 may include one or more other components 138. In some embodiments, the apparatus 102 may be in wireless signal communication with one or more of the sensing device 110, the sensing device 112, the sensing device 114, the proximity sensor 116, the proximity sensor 118, the mobile device 130, or other presentation devices 132.

In various embodiments, a refrigerator 138 may be associated with a fourth sensing device 140. In some embodiments, the fourth sensing device may include a light sensor, shown as Light, that may provide an indication of whether a light associated with the refrigerator is on or off. In some embodiments, a freezer or a beverage cooler, not shown for clarity, may be associated with a sensing device that may be configured similarly to the fourth sensing device 140. In some embodiments, the refrigerator 138, freezer, or beverage cooler may be a commercial appliance given away by a fleet operator or a brand in return for use of the appliance according to a set of agreed terms such as being kept in a particular location, kept in a correct operating range, and stocked with agreed products. In other embodiments, the refrigerator 138, freezer, or beverage cooler may be a home appliance. In various embodiments, rather than using the fourth sensing device 140 that may have multiple sensors, multiple sensing devices, each with a different number of sensors, such as a single sensor, may be associated with the refrigerator 138.

In various embodiments, indirect information (e.g., sensor data) from the fourth sensing device 140 may be used by the apparatus 102 to infer measurements of importance. In some embodiments, the apparatus 102 may determine whether the refrigerator 138 is switched on or off based at least in part on sensor data from the light sensor. In a commercial setting, it may be determined by the apparatus 102 that the refrigerator 138 is switched off in response to sensor data from the light sensor indicating a light associated with the refrigerator 138 is off. In a home setting, it may be determined by the apparatus 102 that a refrigerator door is open in response to sensor data from the light sensor indicating a light associated with the refrigerator 138 is on. In various embodiments, the fourth sensing device 140 may include a microphone, not shown for clarity, to provide sensor data associated with the refrigerator 138 such as the sound of a door opening and/or closing. In some embodiments where the refrigerator 138 may be a commercial refrigerator, the fourth sensing device 140 may be or include a door sensor. In various embodiments, sensor data from the door sensor that may include vibration (e.g., from an accelerometer) and/or sound data (e.g., from a microphone) may be used by the apparatus 102 to detect when a door of the refrigerator 138 is opened and/or closed. In some embodiments, the fourth sensing device 140 and/or other sensing devices associated with the refrigerator 138 may be add-on devices that may be used with an existing refrigerator that may already be deployed in a commercial or home setting. In various embodiments, the apparatus 102 may be located in a cloud computing or server environment. In some embodiments, sensor data from the fourth sensing device 140 may be correlated at an edge of the system such as at a gateway before being sent to a cloud computing environment that includes the apparatus 102. In some embodiments, the apparatus 102 may be configured to recognize appliance states and/or provide recommendations relating to appliances located in multiple remote locations. In various embodiments, the apparatus 102 may record and/or send appliance state and/or recommendation information to one or more designated people monitoring use of the appliances instead of, or in addition to, a user of the appliances. For example, the apparatus 102 may provide appliance monitoring information and/or recommendations to a designated person from a fleet operator or brand that wishes to monitor multiple deployed refrigerators, freezers, and/or beverage coolers that may be in multiple locations.

Some home appliances such as clothes washing machines, clothes dryers, and dishwashers have existed in the marketplace and provided users with conveniences for decades. However, these appliances require user interaction such as filling the washer with laundry, selecting the correct setting, and starting the machine. In various cases, the user may need to interact with the machine again when the cycle is finished to transfer the load of laundry to the dryer. Similarly, with clothes dryers and dishwashers, the user needs to interact with the machine at the beginning of its cycle of operation and when it is finished. Users will often forget about these interactions, such as when a user forgets to empty the washer and transfer the laundry to the dryer. This may result in inefficient laundry flow and in some cases moldy clothes that may require further intervention. Issues with user interaction may also arise when multiple users are interacting with or could potentially interact with the same appliance such as when multiple family members use a dishwasher. In some situations, one of the users, not knowing that the dishes in the dishwasher are clean, may insert a dirty dish on the top rack that drips onto other items on the bottom rack, requiring the load to be run again. Some users may also not follow the best procedures for running times and other interactions with an appliance such as scheduling run times to minimize the annoyance of its loud operation. In various embodiments, the apparatus 102 may assist users in addressing one or more of these issues.

In some embodiments, the appliance state recognition module 122, the response module 124, and/or other modules or components may use an algorithm that may adapt to particular appliances. In various embodiments, one or more modules or components of the apparatus 102 may use crowd-sourced information in making a determination, generating a response, or modeling behavior. In some embodiments, characteristics of an appliance make and model, that may be based at least in part on the appliance model, year of purchase, installment parameters, frequency of usage or, amount of operation hours may be transferred from one apparatus or system location to another that has a similar appliance in order to bootstrap a learning module that may be included in the other components 132 of the apparatus 102.

In various embodiments, the apparatus 102 may determine an optimal point of running an appliance in order to optimize finish time or any other stage of operation that needs user intervention. As an example, if a user loads their washing machine at 10 p.m. and pushes the start button, they may typically not have time to unload it until they wake up in the morning (e.g., based on typical cycle time and previous user behavior), so the apparatus 102 may delay the start time until 5 a.m. (e.g., by sending a delayed start command to an appliance controller), giving ample time for the cycle to finish before the user is awake and can transfer the load to the dryer. By doing so, the apparatus 102 may mitigate the problem of wet clothes sitting in the washing machine for too long. In some embodiments, the apparatus 102 may also factor in energy costs that vary throughout the day. In various embodiments, the apparatus 102 may determine the best time to run a laundry cycle based at least in part on when the cycle will complete as compared to when the user is likely to check the laundry for a next step. In some embodiments, the apparatus 102 may take advantage of a drop in energy cost in between those two times (e.g., overnight). Based at least in part on user preferences, the apparatus 102 may perform similar determinations with respect to the clothes dryer. The apparatus 102 may delay a start time for the dryer to reduce the wrinkle effect from dry clothes sitting in the dryer for too long before removal by a user.

In some embodiments, other sensors such as motion or proximity sensors (e.g., proximity sensors 116, 118) may be used by the apparatus 102 to learn the behavior of different household members. In various embodiments, this feature may be used by the apparatus 102 to assign interventions to different household members who may not know otherwise, unless told explicitly, that the dishwasher needs to be emptied or a laundry load needs to be transferred. For example, a teenage child may be asked to transfer a laundry load to a dryer, a task that they do not usually perform, in response to the apparatus 102 detecting that the child is home before soccer practice and can accomplish the task.

FIG. 2 is an appliance state diagram 200, according to various embodiments. The appliance state diagram 200 shows a plurality of dishwasher states and transition events between states that may correspond to the states of the dishwasher 104 of FIG. 1 in various embodiments. In some embodiments, the state diagram 200 may include an empty/not full state 202, a full state 204, a running state 206, and a done state 208. In some embodiments, items to be washed (e.g., dishes, silverware) may be added to the dishwasher 104 while it is being filled at a first add items event 210 that may both start and terminate at the empty/not full state 202. In various embodiments, a second add items event 212 may start at the empty/not full state 202 and terminate at the full state 204. It should be understood that in various embodiments, the first add items event 210 may occur multiple times before the second add items event 212 occurs during filling of the dishwasher 104, and that in some cases the first add items event 210 may not occur, such as when the dishwasher 104 may be completely filled during a single filling event after it has been emptied. A cycle started event 214 may begin at the full state 204 and end at the running state 206. In some embodiments, a cycle ended event 216 may begin at the running state 206 and end at the done state 208. In various embodiments, an empty dishwasher event 218 may begin at the done state 208 and end at the empty/not full state 202.

In some embodiments, the appliance state recognition module 122 may determine the dishwasher states by keeping track of a current dishwasher state and deter mining whether transition events have occurred, resulting in transition to a next dishwasher state which becomes the current dishwasher state after the state transition. In some embodiments, the appliance state recognition module 122 may use a probabilistic model in determining a current state and/or whether transition events have occurred. In various embodiments, the appliance state recognition module 122 may determine cycle started and/or cycle ended states based at least in part on temperature data from one or more temperature sensors such as described below with respect to FIG. 3. In some embodiments, the appliance state recognition module 122 may detect a transition from the done state 208 to the empty/not full state 202 based at least in part on data from a movement sensor such as an accelerometer.

In various embodiments, the appliance state recognition module 122 may detect a door opening motion based at least in part on accelerometer data. In some embodiments, the appliance state recognition module 122 may determine a duration of time the door was open to estimate whether the door was open enough during one session, or cumulatively over multiple sessions, for the dishwasher 104 to have transitioned from an empty state to a full state while in the empty/not full state 202. In various embodiments, the appliance state recognition module 122 may also determine whether one or more racks of the dishwasher 104 have been rolled out of the dishwasher 104 based at least in part on the accelerometer data.

In similar fashion to that described with respect to the dishwasher states and transition events, the appliance state recognition module 122 may detect events and/or determine states for the clothes washer 106, the clothes dryer 108, and/or other appliances in various embodiments. In some embodiments, the appliance state recognition module 122 may extract a set of features based at least in part on temperature and/or motion data from the sensors. In various embodiments, while the machines are running, vibration from the door and temperature may be detected and used to determine the beginning of a cycle by the appliance state recognition module 122. For some cycles, such as a gentle cycle on the clothes washer 106, movement may stop for an extended duration during the cycle. In various embodiments, the appliance state recognition module 122 may continue to detect the cycle by initially detecting the door was open and closed, detecting vibration from the initial phase (water filling and some movement). At this point in time, a confidence level of cycle detection may be high, and the appliance state recognition module 122 may age the confidence level as time goes by. As the cycle periodically moves the clothes, the appliance state recognition module 122 may reinforce detection and confidence level of the cycle state.

FIG. 3 is a sensor data diagram 300 showing a comparison of temperature data that may be used to recognize an appliance state, according to various embodiments. A first temperature data series 302 from a first temperature sensor (e.g., temperature sensor of sensing device 110) and a second temperature data series 304 from a second temperature sensor (e.g., temperature sensor of sensing device 112) may be used by the appliance state recognition module 122 in some embodiments. In various embodiments, the first temperature data series 302 may represent temperature data from a temperature sensor associated with a dishwasher and the second temperature data series 304 may represent temperature data from a second temperature sensor that may be associated with a laundry appliance (e.g., a clothes washer or a clothes dryer), a laundry room, or a temperature sensor in some other location in various embodiments.

In some embodiments, the appliance state recognition module 122 may be to determine whether a cycle has started and/or a cycle has ended based at least in part on comparing the first temperature as measured by the first temperature sensor to the temperature measured on the second temperature sensor. In various embodiments, the appliance state recognition module may use a thresholding event detection mechanism on the temperature stream of the first and second temperature data to detect the beginning and end of a dishwasher cycle. In some embodiments, a first predetermined threshold difference may be used by the appliance state recognition module 122 to determine a cycle has started when the first temperature exceeds the second temperature by at least the first predetermined threshold difference. In various embodiments, a second predetermined threshold difference may be used by the appliance state recognition module 122 to deter mine a cycle has ended when the first temperature exceeds the second temperature by less than the second predetermined threshold difference after a cycle has started. In some embodiments, temperature spikes in the data from the first and/or second temperature sensors may be filtered such as by using a moving average of the temperature data.

FIG. 4 is a block diagram of a system 400 that may include one or more components of the appliance state recognition apparatus 102 described with respect to FIG. 1, according to various embodiments. In some embodiments, the system 400 may include one or more sensors 402 (e.g., one or more of temperature, accelerometer, or contact sensors of sensing device 110, 112, 114 and/or proximity sensors 116, 118) that may provide sensor data to one or more of an appliance state detection subsystem 404 and/or a user behavior profiling subsystem 406. In various embodiments, the appliance state detection subsystem 404 may include the appliance state recognition module 122 described with respect to FIG. 1 or similar functionality. In some embodiments, the behavior profiling subsystem 406 may include the behavior modeling module 134 described with respect to FIG. 1 or similar functionality.

In various embodiments, a recommender subsystem 408 may be coupled with and/or receive data from the appliance state detection subsystem 404 and the user behavior profiling subsystem 406. In some embodiments, the recommender subsystem 408 may include the response module 124 and/or the transmission module 126 described with respect to FIG. 1 or similar functionality. The recommender subsystem 408 may also be coupled with and/or receive data from one or more external sources 410 such as a weather information source, a news source, or a calendar of a user in some embodiments. In various embodiments, the recommender subsystem 408 may direct an appliance controller 412 based at least in part on one or more communications from the appliance state detection subsystem 404, the user behavior profiling subsystem 406, and/or the external sources 410. In some embodiments, the recommender subsystem 408 may generate a recommendation to be presented on a presentation device (e.g., mobile device 130 or other presentation device 132) in addition to, or instead of, directing appliance controller 412.

In various embodiments, one or more subsystems or components of the system 400 may acquire data from the sensors 402, detect one or more appliance states, and use that information with a user's profile and current presence information to determine the best time and series of events for running the one or more appliances. In some embodiments, the appliance controller 412 may provide for control of a start time of an appliance with which it is associated. In embodiments where an appliance does not support such a control mechanism, information may be sent to a user by the recommender subsystem 408 with respect to one or more recommended actions and their timelines. In various embodiments, the recommender subsystem 408 may consider other events in generating a recommendation such as weather, news, and personal or family calendars when access to such data is provided. In some embodiments, the recommender subsystem 408 may use correlations of appliance activity with these external factors to better model user behavior and offer more personalized assistance for a household.

FIG. 5 is a flow diagram illustrating a method 500 of recognizing an appliance state and determining a response, according to various embodiments. In embodiments, some or all of the method 500 may be practiced by components shown in the operating environment 100 and/or the system 400, that may include components of the apparatus 102, described with respect to FIG. 1 and/or subsystems or other components of the system 400 described with respect to FIG. 4.

In some embodiments, the method 500 may include identifying sensor data in one or more signals relating to data from one or more sensors associated with an appliance (e.g., dishwasher, clothes washer, clothes dryer) at a block 502. In some embodiments, the sensor data may include one or more of motion data or temperature data (e.g., from a temperature sensor or accelerometer of sensing device 110, 112, or 114). In some embodiments, the sensor data module 120 may identify the sensor data. In various embodiments, the method 500 may include determining an appliance state of the appliance based at least in part on the sensor data at a block 504 (e.g., with appliance state recognition module 122 or appliance state detection subsystem 404).
